This happens because DECLARE_ZORBA_MODULE() uses a glob pattern to find all .cpp files in the module's source directory. When you make a change which adds new .cpp files, as you did here, it's unfortunately necessary to re-run CMake. There's no way CMake can detect this change automatically, so it doesn't build the new files. I tried doing your experiment and was able to reproduce the bug (it actually gave a runtime linking error after updating to r10491, but I'll put that down to an OS difference). Then I tried it again but adding a call to "cmake" after updating to r10491, and the query ran fine.
CMake recommends against using glob patterns for naming source files for exactly this reason, but I couldn't think of any other way to make a general-purpose DECLARE_ZORBA_MODULE() macro. I suppose it could take a list of source files rather than doing a glob pattern... hard to know whether this would be an ease-of-use improvement or not. What I certainly will do, though, is update the documentation to indicate this problem, and to instruct users to re-run CMake after adding any new .cpp files. ** Changed in: zorba Status: New => Confirmed ** Tags added: doc ** Changed in: zorba Milestone: None => 2.1 ** Changed in: zorba Importance: Undecided => Medium ** Summary changed: - inconsistent build and install directories + doc: re-run CMake after adding module .cpp files -- You received this bug notification because you are a member of Zorba Coders, which is the registrant for Zorba. https://bugs.launchpad.net/bugs/872386 Title: doc: re-run CMake after adding module .cpp files Status in Zorba - The XQuery Processor: Confirmed Bug description: I have refactored a few classes in the http_client module and brought the CMake build directory in an inconsistent state with the install directory. That is, running any query using the http-client module I got this error: zerr::ZXQP0028_TARGET_NAMESPACE_NOT_PROVIDED. And this without changing the module URI. This look like a problem in the cmake build system around the modules (in this case only internal ones) and the loading of those form the install/build directories. To solve this I had to delete from the build directory: - zorba_modules/zorba_http-client_module - modules and the install directory To replicate this, try: - build from lp:~gabipetrovay/zorba/cpp-xml-parsing rev. 10490 - (n)make install - run a query from install directory and make sure that it runs (at r.10490 you will get a segmentation fault but that is another problem and a sign that it find the module) - update to rev. 10491 - run cmake and build again - (n)make install - now running the query again you should get: zerr::ZXQP0028_TARGET_NAMESPACE_NOT_PROVIDED - deleting the directories above will solve the problem To manage notifications about this bug go to: https://bugs.launchpad.net/zorba/+bug/872386/+subscriptions -- Mailing list: https://launchpad.net/~zorba-coders Post to : email@example.com Unsubscribe : https://launchpad.net/~zorba-coders More help : https://help.launchpad.net/ListHelp
